Postpartum hemorrhage
Two trials that only included nulliparous women provided data on this
outcome. The result of meta-analysis indicated that women in lubricant
group had no statistically difference in postpartum hemorrhage when
compared with those in standard care group (MD -41.06 ml, 95%CI -112.47
to 30.35; I2=95%) (Figure S30). There was
insufficient data for subgroup analysis.
